The co-formation of diarylalkane by-product in the haloalkylation of an aromatic compound with an ether corresponding to the formula R-O-R′, wherein R is an α-haloalkyl group containing at least two carbons and R′ is R or alkyl, is minimized by conducting the reaction with agitation in the presence of both hydrogen sulfate and a hydrogen halide.
在芳香族化合物与对应于式 R-O-R′ 的醚进行卤代烷基化反应时,通过在硫酸 氢和卤化氢存在下搅拌进行反应,可最大限度地减少二芳基烷烃副产物的共生成。
